US 8,619,841 B1 · Transceiver with carrier frequency offset based parameter adjustment

Abstract

A transceiver configured to be implemented in a first device includes transmitter and receiver modules and first and second estimator modules. The receiver module receives a first signal transmitted on a channel from a second device to the first device. The first estimator module estimates a first parameter associated with the first signal or the channel. The second estimator module estimates a carrier frequency offset based on the first parameter. The carrier frequency offset is a difference between a first carrier frequency of the first device, and a second carrier frequency of the second device. The transmitter module adjusts a second parameter based on the carrier frequency offset, and based on the second parameter, transmits a second signal to the second device or the receiver module adjusts a third parameter based on the carrier frequency offset, and based on the third parameter, receives a third signal from the second device.
